INSPECT THE CABIN HEATER RELAY TERMINALS AND WIRE HARNESS FOR A CONDITION CAUSING
HIGH CIRCUIT RESISTANCE
Disconnect the Cabin Heater Relays.
Disconnect the TIPM C11 harness connector.
Inspect the connector terminal for signs of corrosion build up and dam-
age.
Visually inspect the wiring harness for any chafed, pierced, pinched or
partially broken wires hidden in the wire insulation.
Were any of the above conditions found?
Yes
>> Repair as necessary.

CHECK THE (F937) FUSED IGNITION SWITCH OUTPUT (RUN) CIRCUIT FUNCTION
Connect one end of a jumper wire to the (F937) Fused Ignition Switch
Output (RUN) circuit at the Heated Seat Module harness connector, and
connect the other end to a clean chassis ground.
NOTE: The test light should be illuminated and bright. Compare
the brightness to that of a direct connection to battery.
Using a 12 volt test light connected to 12 volts, probe the (F937) Fused
Ignition Switch Output (RUN) circuit in the TIPM C8 harness connector.
Does the test light illuminate brightly?
Yes
>> Go To 5
No
>> Repair the (F937) Fused Ignition Switch Output (RUN) cir-
cuit for high resistance.
